VIOLIN.

SPECIFICATION forming part of Letters Patent No. 627,186, dated June 20,1899. Application filed February 8, 1898. Serial No. 66 9.5 70. (N0model.)

To all whom it may concern:

Be it known that I, HERMAN HAGBERG, a subject of the King of Sweden andNorway, (but having declared my intention to become a citizen of theUnited States,) residing at Brainerd, in the county of Crow WVing andState of Minnesota, have invented certain new and useful Improvements inViolins and other Stringed Instruments, of which the following is aspecification.

My invention relates to improvements in the structure of orchestralinstruments of the violin kind wherein the vibration is caused by meansof the bow, which vibration of the strings placed in contact with thesoundingboard is reinforced by the air held in the body of theinstrument; and my invention has for one of its objects to remove fromthe body of the instrument any obstacles to the free and regularvibration of the sounding-board.

Another object of my invention is to give greater strength andsonorousness to the instrument, united with greater equality anduniformity of the purity of tone.

Another object of' my invention is to give a new instrument the tone andeffect which a hundred years use is now required to produce, thus addinggreatly to its value.

These objects I accomplishin the manner and'by the means hereinafterfully described in detail, and particularly pointed out in the claims,reference being had to the accompanyin g drawings, in which thereference-letters indicate like parts in both figures.

Figure 1 is a central longitudinal section of my invention. Fig. 2 is across-section on line w w of Fig. 1.

My invention consists in extending the lining A of the sides B of theviolin from the upper bracket-brace C, to which the neck of. theinstrument is attached in the usual way, to the lower bracket-brace O oneach side of the violin, crossing the open mouths of the four bows D onthe sides of the violin at the waist on the line of the curve from thepoint where said lining A leaves the side B of the violin on one side ofsaid mouth of said bow D to where said lining A again meets and followsthe curves of'the side B of the violin. At the top and bottom, betweensaid lining A and said sides B of the violin, narrow strips E,one-quarter inch thick, are inserted, to which strips E both said liningA and said sides B are securely glued. Air-spaces F, one-quarter inchwide and nearly equal in height to the sides B of the violin, are formedall along the sides B of the violin except at the bows D, which areentirely open. When the top and bottom of the violin are put on, theyrest on the lining A, sides B, and strips E and close the open bows Dboth top and bot tom. This construction so strengthens the sides B thatwood thinner, and therefore more responsive to vibrations, may be usedfor the sides B and lining A and the corner-blocks d,

upper bracket-brace O, and lower bracketbrace C may be smaller and takeup less room. The operation of my invention is as follows:

The greater regularity in form ofthe interior of the body of the violincauses more regularity and uniformity in its tone and the greaterresilience of the sides B, reinforced by the aircushion there, givesgreater strength and sonorousness to the sound, and both combined tendto prolong the oscillations of the air in the body of the instrument,the sound ing-board, and the strings, thus increasingthe harmonics.

My invention can be applied either to old or new instruments.

Having thus described my invention, what I claim as new, anddesire tosecure by Letters Patent, is

1. In a violin-body, a lining around the inside of said violinapproximately parallel to the rim and a short distance from said rim,said lining extending from the top to thebottom of said violin andacross the corner-bows, not into them, substantially as shown and described.

2. In a violin-body, strips placed between the lining and sides of suchbody at the top and bottom, said lining extending across the mouths ofthe corner-bows, not into them, substantially as shown and described.

In testimony whereof I hereto aflix my sig nature in the presence of twowitnesses.

HERMAN HAGBERG.
